If you’ve ever stared at a plain fridge, covered in nothing but random grocery lists and faded takeout menus, and wished it had little bits of your favorite moments scattered across the door—then resin fridge magnets with photos are the perfect DIY (or bulk, if you’re buying them to resell or gift) project you need. As a resin fridge magnet supplier who’s spent the last 7 years experimenting with every trick, mistake, and hack in the book, I’ve made hundreds of these little memory holders—some that stayed perfect for years, others that turned yellow, bubbled, or peeled so bad I wanted to toss the whole batch. Today, I’m sharing the exact, science-backed steps to make resin fridge magnets with photos that actually last, plus a few tips if you want to order custom ones in bulk for your business or loved ones. Resin Fridge Magnet
First, let’s get one thing straight: making resin magnets with photos isn’t just pouring resin over a picture and hoping for the best. The biggest mistake most people make is skipping the prep work that keeps the photo from fading, peeling, or bubbling. Resin is great, but it’s a harsh chemical that can break down paper and photos over time—especially if they’re left in a humid place or sit in direct sunlight. So before you touch any resin, you need to pick the right photo and seal it properly.
Not all photos work equally well. If you’re using a regular home printer photo, or a phone print from a drugstore, stick to high-quality glossy or semi-glossy photo paper. Matte paper is a no-go here—it absorbs resin and turns mushy, leaving you with a blobby mess that falls apart in a month. Also, avoid photos with a lot of text or tiny details, like group shots where each person’s face is the size of a pea. Resin will soften the edges of small details, so aim for photos that are at least 2×3 inches (standard wallet size works great) with clear, sharp subjects. If you’re cutting your photo to fit your magnet mold, leave a 1/8 inch border around the edges—this gives you room to work without accidentally cutting off part of your picture when you trim the resin later.
Next up, sealing the photo. This is the most critical step to prevent fading. I use two methods, depending on whether I’m making small personal batches or bulk orders for clients. For personal projects: grab a clear, matte or glossy acrylic sealer (the kind used for crafts, not spray paint) and give the entire front and back of your photo two light coats, letting each coat dry completely for 15 minutes between sprays. Wait, two coats on both sides? Yes—this creates a protective barrier that stops resin from seeping into the paper fibers, and blocks UV rays which cause photos to yellow over time. For bulk orders, I’ve tested laminated photos too, and that works well, but make sure the lamination is a thermal lamination (not pressure-sensitive) because it creates a tighter seal. The only downside of lamination is that it can leave a slight plastic texture if the lamination isn’t done evenly, so I prefer spray sealer for a smoother, more polished finish.
Once your photo is sealed and cut to size, it’s time to pick your supplies. You don’t need fancy equipment, but sticking to the right resin type will save you a lot of frustration. I always use non-toxic, art-grade epoxy resin, not the cheap hardware store resin for projects like countertops. Hardware store resin is often more likely to yellow over time, and it cures too fast if you’re working on small, detailed projects. Look for a resin that’s labeled “low-odor” and “UV-resistant” for the best results—this keeps your photo from fading even if the magnets are on a fridge in direct sunlight. You’ll also need: silicone magnet molds (these are cheap and reusable, and silicone makes it easy to pop the finished magnet out without scratching it), strong neodymium magnet discs (10mm or 15mm diameter works best—they’re strong enough to hold a grocery list and won’t rust), mixing cups and stir sticks (disposable ones are easier for small batches), a small torch or heat gun (to pop air bubbles in the resin), rubbing alcohol and cotton pads (to clean up drips), and a level.
Now, let’s talk about the science of mixing resin. Resin cures when you mix two parts: resin and hardener. The ratio is almost always 1:1, but always follow the manufacturer’s instructions—too much of one part and it’ll stay sticky forever, too little and it’ll cure lumpy or yellow. I pour equal parts into a disposable cup and stir slowly for 2 minutes, scraping the sides and bottom of the cup every 30 seconds. If you stir too fast, you’ll create tiny air bubbles that get trapped in the resin and show up as tiny holes in your finished magnet. After mixing, let the resin sit for 5 minutes—this lets most of the surface bubbles rise to the top, so you can pop them easily.
Now for the actual pouring step, which is where most people mess up with the photo placement. Here’s the rule: never pour a thick layer of resin first and then lay the photo on top. That causes the photo to shift, bubble, or float to the surface. Instead, pour a thin base layer of resin (about 1/8 inch thick) into your silicone mold, then place your sealed photo face-down onto the wet resin. Use a toothpick to gently press out any air bubbles that get trapped between the photo and the resin—push slowly, don’t tear the photo. Let this base layer cure for 30 minutes (check your resin’s instructions, it might be 20 or 40 minutes) until it’s tacky to the touch, not fully hard.
Once the base layer is tacky, it’s time to pour the top layer. This layer will cover the photo and create that smooth, glossy finish that makes resin magnets look professional. Mix your next batch of resin, pour it slowly over the photo, filling the mold to the top. You want the resin to be just slightly above the edge of the mold, so when it cures, it creates a slight dome that makes the magnet look polished, not flat. Now, this is where the torch or heat gun comes in. Hold the torch about 6 inches above the resin, moving it in a circular motion, and you’ll see tiny bubbles pop to the surface in seconds. Don’t hold the torch too close—you’ll burn the resin, leaving yellow spots. If you don’t have a torch, you can use a straw to blow gently on the surface, but that works slower.
After you pop all the bubbles, place your mold on a level surface and let it cure fully. Curing time varies—most resin is fully cured in 24 hours, but it’s better to wait 48 hours if you can. If you try to demold it too early, it will be soft and bend, ruining the photo. Once it’s fully cured, pop the magnet out of the silicone mold—silicone makes this super easy, just twist the mold gently and the magnet will slide right out.
Now, add the magnet back. You might be tempted to use regular adhesive to stick the neodymium magnet to the back, but regular glue doesn’t bond well to cured resin, especially if the back of your magnet is slightly textured. The best adhesive I’ve tested is E6000 craft glue—it’s strong, waterproof, and dries clear. Put a small dot of glue on the center back of your resin magnet, press the neodymium magnet onto it, and hold it for 30 seconds. Let it dry for 24 hours before using it on a fridge.
If you’re making these to sell or give as bulk gifts, there are a few extra tips that make the process faster and more consistent. I usually pre-cut my photos in bulk, seal them in batches, and mix resin in larger amounts for orders of 50 or more. I also use custom molds if I have a set design—like hearts, circular shapes, or even custom shapes of animals or logos—to make the order look uniform. One thing to note: if you’re working with bulk orders, order extra resin. It’s better to have a little leftover than to run out halfway through and have to mix a new batch, which can have slightly different curing times and colors.
Wait, I should also talk about common mistakes I’ve made over the years, so you don’t have to repeat them. Last year, I made a batch of 100 magnets for a local café, and I forgot to seal the photo backs. By the end of the first month, half of them had peeled at the edges because moisture got under the photo from the fridge. Another time, I mixed resin too fast, and there were hundreds of tiny bubbles all over the photos—my customer had to send most of them back, which cost me time and money. The biggest mistake people make is using regular printer paper instead of photo paper—those magnets start to turn brown within a week, and you can tell the photo is dying.
As a resin fridge magnet supplier, I’ve also learned that people don’t just want a magnet with a random photo. They want magnets that feel personal—so if you’re ordering for a wedding, for example, customers often want photos from their engagement session, or shots of their wedding party. For family gifts, it’s usually photos of kids, pets, or vacations. The good news is that our process is flexible—we can do small batches of 10 magnets up to bulk orders of 500, with custom shapes, sizes, and finishes. Every magnet we make follows the same prep and curing steps I mentioned, so you can trust that they’ll last for years, not just a few months.
If you’re new to making these at home, start with a small test batch first. Make 2 or 3 magnets to practice sealing the photos, mixing the resin, and popping bubbles. Once you get the hang of it, you can scale up to larger batches. And if you’re looking to order custom resin fridge magnets for your business, as gifts for your employees, or just to have a bunch of your favorite memories, we can work with you on size, design, and volume. We’ve worked with small businesses, nonprofits, and individual customers, so whatever your needs are, reach out to discuss your project.
